Charpy Impact Testing Machine

Charpy V and U notch pendulum impact testers to ISO 148 and ASTM E23

Impact Testing Machines · Charpy

A Charpy impact testing machine strikes a simply supported, notched specimen with a pendulum and records the energy absorbed in breaking it. The Charpy V-notch test is the standard toughness test for steel plates, pipes, forgings and weld procedures, often carried out at sub-zero temperatures.

We supply analogue, digital and fully automatic Charpy testers, including the IT 30 series and the Auto Impact range, together with cooling chambers, notch broaching machines and Charpy CRM specimens.

Charpy testing checklist

  • Prepare specimens to the standard dimensions (usually 10 x 10 x 55 mm)
  • Cut V or U notches with a broaching machine and verify notch geometry
  • Condition specimens at the test temperature in a cooling chamber
  • Transfer and break the specimen within the time limit specified by the standard
  • Verify the machine periodically with reference specimens

Frequently Asked Questions

What is a Charpy V-notch test?

It is a pendulum impact test on a specimen with a 2 mm deep, 45 degree V-notch, used to measure the toughness of metals.

Can the same machine do Charpy and Izod tests?

Yes. Our IT 30 and Auto Impact machines perform both, using different pendulum positions and specimen supports.

Why test at low temperature?

Many steels become brittle at low temperatures. Sub-zero Charpy tests confirm the steel remains tough at its service temperature.
